To a, when], it Ill/(11y concern;

Be it known that I, JOHN A. FERGUSON, a citizen of the United States of America, and a resident of Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Fireproof Buildings, of which the following is a specification.

This invention relates to certain new and useful improvements in fireproof-building construction; and it has for its object, among others, to provide a fireproof building or wall in which the joist-supports are supported on the arms or webs of the building-blocks of which the wall is composed. By this means there is no settling, and the joist-support may receive the ends of the joists direct, or the joist may be provided with metallic hangers, which may engageover or upon the joistsupport. The inner face of the Wall may be lath and plaster, or wood, metal, or other sheathing, as may be found most expedient or desirable. The joist-support may be of any suitable material and shape in crosssection, and as it rests directly upon the webs of the building-blocks it is held against settling, and in some instances it may be held firmly against movement inward or outward by any suitable provision.

Other objects and advantages of the inven tion will hereinafter appear, and the novel features thereof will be specifically defined by the appended claim.

The invention in its preferred form is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which Figure 1 is a top plan of a portion of a wall, showing my present improvement. Fig. 2 is a perspective detail showing the inner face of the finished wall, the joist-support being indi cated by dotted lines. Fig. 3 is a perspective detail showing a joist with its hanger supported on the joist-support. Fig. 4 is a perspective detail showing a building-block with its arms or webs provided with recesses receiving the joist-support to prevent movement of the latter at right angles to its length.

Like numerals of reference indicate like parts throughout the several views.

Referring now to the details of the draw ings, l designates building-blocks, of cement or the like, having webs or arms 2, said blocks being laid in the wall in the usual manner, the outer faces forming the outer face of the wall, while the inner ends of the arms or webs receive the lath and plaster or whatever finish it may be desired to give to the inner wall.

3 is a joist-support of any suitable material and of any desired size and shape in cross-section. It is supported on the arms or webs 2 of the blocks at the proper points and is de signed to support the joists 4. These joists may rest directly upon the support 3, as seen at the left of Fig. 1, or the joist maybe provided with metallic hangers 5, as seen at the right of said Fig. 1 and also in detail in Fig. 3.

In some cases it may be found desirable to provide or form the webs or arms of the blocks with cavities or recesses, as seen at 6 in Fig. 4, into which the joist-supports are received, and thus held against movement at right angles to its length, and this will serve to prevent bulging of the walloutward or of its being pulled inward by the strain on the floor.

The inner face of the wall may be prepared in any suitable Way. For instance, there may be secured to the inner faces of the webs or arms 2 metal sheets 7, which may be held to the said arms or webs in any suitable manner, as by the metal ties 8, either molded in the arms or laid in the cement mortar between the arms at the joints, the ends of the ties being passed through the metal sheets and bent to hold the sheets to the arms. Upon this perforated sheeting plaster 9 may be placed in the usual way. Other forms of finish may be employed without affecting the feature of the joist-support resting on the webs or arms of the blocks.

What I claim as new is A wall composed of building-blocks having webs, a separate member supported directly upon said webs, and joist directly supported upon said member.

Signed by me at Denver, Colorado, this 27th day of April, 1906.

JOHN A. FERGUSON.
